6 Claims. 1

This invention relates to. a purifier for liquids and more particularly to a liquid purifier in which the bacteria is electronically removed;

It is"an objectof the instant invention to simplify the purification of liquids.

A further object is to provide an electronic purifier that can remain in operation for relatively long periods of time with servicing.

Still another object is to provide an electronic purifier that is readily serviced.

It is also an object of the instant invention to provide an electronic purifier that is of simple construction and requiring little space.

Other objects of the instant invention .Will become apparent in the course of the following specification.

In the accomplishment of these objectives, the

electronic liquid purifier may bemade with an' irradiating chamber "toward the base of which is an intake port and toward the'top'an outlet port for any liquid. Anelectronic lamp of the germicidal variety is inserted in an inverted position in the chamberwith the base of the lamp and the coacting socket suitably protected from the liquid.- The bottom of the irradiating chamber may be made removably and upwardly'therein is inserted an irradiating partition so formed that the lamp extends downwardly therethrough. By making the passageway between the lamp and the partition narrow, all the liquid entering the base of the chamber is brought in substantial contact with the glass of the lamp. The'usual electrical components for actuating the lamp may be mounted in'a separate compartment above the irradiating chamber, and a removable transparent bacteria trap at the base of the chamber permits ready inspection and servicing of the device.

The invention will appear more clearly from the following detailed description when taken in connection with the accompanying drawings showing, by way of example, a preferred embodi-- ment of the inventive idea.

In the drawings Figure 1' is a front elevational view of the electronic: liquid purifier constructed in accordance with the principles of this invention.

Figure 21s a sectional view along the vertical center line of thepurifier shown inFigure 1.

Referring now in greater detail to thedraw ings in which like reference numerals-indicate like parts,- reference numeral 1 indicates the irradiating chamber, I i! compartment,

6:the electronic lampaof the germicidal variety.

the electrical component I 4 the irradiating partition, and- 2. the hollow cylindrical member open base and atop member J9 formed integral with the cylindrical member l8 .or, otherwise as desired. Toward. the baseofthe cylindrical mem-. ber- !Bis the liquid intake. port andtoward the top the liquid outlet port 2 l.

The electronic lamp, 6 of the germicidal variety is. supported by the socketiiin an inverted position within the chamber 1 as shown in Fig ure.2. The socket. 8is secured to the-top member HLwith the-gasket ZZandthe-sCreWs 34 and 35 which prevents the liquidfrom comingin contact:with: the electrical connections of both the socket-8: and lamp '6 orrleaking ,outof the top of the chamber I.

Through the openbaseof the cylindrical mem 18 having an her it, the: irradiating partition 14 is inserted."

\ The partition M-.-coinprises ahollow cylindrical Theirra'diating chamber! may be-formed withmember 38 having anopen; baseand open top and a hollowcone frustum. 23 with openbase and top superposed .on the upperrim thereof; The diameter of the cylindrical memberv 38Lisdesigned so thattha-partition M'fits snugly against the inside-= surface: portion of the. member [8 when inserted andanzopening is left in theside toregistenwith the-.intakeport :26. A nipple 24 with turned up rim maybeinserted through the alinedopenings andthreaded into another nipple secured between a shut-.oirvalve Il'in the pipe line and the wall of the cylindrical hold :thepartition :Hiv in position which permits the partition tob'e readily removed for cleaning and-the like. The diameter of the top of the frustum 23 is sufficient to permit the'lamp Bto be inserted therethroughas shown in Figure 2 and leaving arelatively small space 25 therebetween; In this way,-allth'eliquid entering the base of theirradiati-ng chamber I through the inlet port 29 is forced upwardly by the partition Hi inclose proximity to 'the-"glass of the lamp 6' before passing to the upward part of the chamber and-seekingthe-outlet port 2|. The irradiating partition It -is preferably made ofhighly reflective material such as alzak alumi num or'highly polished chrome or the like.

Over the'openbases of 'the'irradiating chamber l and'lthe irradiatingpartition I 5, the base can 261s removablysecur-ed by ed portions. is the bacteriatr'ap which may be made of any coastin threadsuit'able transparent material with an outwardly turned upper'rim'for fitting intca coacting aper ture in-the bottom of the-cap 26' where it isjsecured between thegaskets 3 bythe-nut 5 thread--' member It to At the bottom-of thebase cap Et ed into a coacting tap on the inside surface portion of the cap 26.

The faucet !5 may be secured to the outlet port M by any suitable means.

A cover 21 or the like may be screwed into the top rim of the irradiating chamber I as shown in Figure 2 for protecting the electrical parts of the socket 8 and for supporting the electrical component compartment ill, later described, by the nipple 28 threaded into coacting taps between the chamber and compartment. Suitable electrical conductors 29 are electrically connected to the usual prongs 30 of the socket 8 and extend upwardly through the nipple 28 to the components as shown in the following paragraph.

The component compartment comprises a housing 3| disposed around the transformer II which is secured therein by any suitable means. The housing 31 is attached at the base by the nipple 28 to the irradiating chamber 1 as previously shown. At the top of the, housing 3i is an opening 32 for the removable insertion of the starter E2 which is in a convenient location for replacement whenever necessary. Through one side of the housing 3! is the switch I6 and through the opposite side the cable l3 shielding the conductors leading to any suitable source of electrical power. The conductors 29 and the like leading from the prongs 39 of the socket 8 to the switch [6, transformer ll, starter l2, and thence to the source of electrical power are connected in the usual and well known manner for lamps of the type described.

The operation of the electronic purifier is as follows: The switch I6 is turned to the on position which in coaction with the transformer H and starter l2 causes the lamp 6 to give off the purifying rays. The faucet I is then turned to the on position and the liquid or water from the pipe line 33 under pressure passes through the shut-cit valve ll, which has previously been turned to the on position, thence through the inlet port into the lower chamber 36, thence upwardly, directed by the irradiating partition l4 toward the glass of the lamp 6 by virtue of the narrow opening in the top of the partition [4 into the upper chamber 31, toward the outlet port 2|. If desired, the switch l6 may be turned to the on position only when the faucet I5 is open or about to be opened. When servicing the purifier, the shut-off valve 11 is moved to the closed position, the base cap 26 unscrewed, the nipple 24 removed which releases the irradiating partition 54 to be slipped out of the chamber l. Thus removed, all parts of the chamber I are readily cleaned and replaced.

It is apparent that the specific illustrations shown above have been given by way of illustration and not by Way of limitation and that the structures above described are subject to wide variation and modification. Without departing from the scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.
